i installed led turn signal lights on my new 2016 super duty platinum but as i expected im now getting the rapped flash!

i know this can be fixed with load resisters but they heat up (can be a fire hazard) and defeat the point of changing to leds, (less power load)

on older cars the proper way to fix this is changing out the flasher relay to a led flasher but now the computer handles this without a flasher.

i herd somewhere that a simple re-flash/program at ford will fix this but when i went to my dealership service department they never herd of anything like this! could it just be something they haven't done yet at this dealer ship or am i miss informed?

thank you, this worked and they did it free for me, but now I have another problem, the bulb I'm using is a amber/white switchback LED, and when the truck isn't running it works perfectly but when running it stutters and misses beats wile running with marker lights on (switchback) and when I run with marker lights off (so just amber signal flashes) it will flicker during each flash. I don't have a tester but I'm thinking this is a power level problem, any ideas? I know its not a lot to go by
